Abstract
A method for calibrating an optoelectronic component having a light emitter/receiver unit and a connection unit includes the steps of setting an initial relative position of a first part and a second part of the connection unit. After that, the first part is displaced in a reference plane relative to the light emitter/receiver unit. Next, the first part is affixed to the light emitter/receiver unit. Then the second part is displaced relative to the first part and is also affixed to the light emitter/receiver unit. An optoelectronic component is also provided.
Claims20
A method for calibrating an optoelectronic component, the method which comprises:
- providing a light emitter unit having a light emitter for transmitting a beam of light along a first direction;
- providing a connection unit including a first part and a second part, the first part having a deflection mirror, the second part provided for mounting a fiber-optic wave guide and being displaceable toward and away from the deflection mirror relative to the first part;
- providing an optical element disposed in a beam path between the light emitter and the second part;
- turning on the light emitter;
- setting an initial relative position between the first part and the second part;
- calibrating the first part relative to the light emitter unit, while maintaining the initial relative position between the first part and the second part, by displacing the first part in a structurally predetermined reference plane intersecting the first direction, such that the beam of light strikes the deflection mirror and a deflected beam of light leaves the deflection mirror, the deflected beam of light striking an end face of the fiber-optic wave guide essentially centrally in a second direction extending essentially parallel to the reference plane;
- fixing a relative position between the first part and the light emitter unit in a first calibrated position;
- calibrating a the second part relative to the first part by displacing the second part in the second direction relative to the first part such that a given condition with respect to a location of an optical image plane of the optical element relative to a location of the end face of the fiber-optic wave guide is met;
- and
- fixing a final relative position between the first part and the second part in a second calibrated position.

- turning on an external light emitter coupled to the fiber-optic wave guide at a free end thereof such that the beam of light leaves the fiber-optic wave guide along a second direction;
- turning on the light receiver;
- setting an initial relative position between the first part and the second part;
- calibrating the first part relative to the light receiver unit, while maintaining the initial relative position between the first part and the second part, by displacing the first part in a structurally predetermined reference plane intersecting the first direction and being essentially parallel to the second direction, such that the beam of light strikes the deflection mirror and a deflected beam of light strikes substantially centrally an opening cross-sectional face of the light receiver in the first direction;
- fixing a relative position between the first part and the light receiver unit in a first calibrated position;
- calibrating the second part relative to the first part by displacing the second part in the second direction relative to the first part such that a given condition with respect to a location of an optical image plane of the optical element relative to a given location of the opening cross-sectional face of the light receiver is met;
- and
- fixing a final relative position between the first part and the second part in a second calibrated position.
